  public static void main(String[] args){
    System.out.println("Hello World");
  }//end main
}//end class

Back to Question 6

Answer 5

True. Although a variety of IDEs are available that can be used to compile and run Java applications, the most fundamental way is to compile and run the programs from the command line. A batch file in Windows, or the equivalent in other operating systems, can be of some help in reducing the amount of typing required to compile and run a Java application from the command line.

Back to Question 5

Answer 4

False. Java uses huge class libraries, which few if any of us can memorize. Therefore, it is very difficult to program in Java without access to the documentation for the JDK.

As of November 2012, several different types of Java documentation are available online at http://www.oracle.com/technetwork/java/javase/documentation/index.html .

Back to Question 4

Answer 3

True. Installing the Java JDK can be a little difficult depending on your experience and knowledge. As of November 2012, you will find installation instructions at http://download.oracle.com/javase/7/docs/webnotes/install/windows/jdk-installation-windows.html .

Back to Question 3

Answer 2

True. You will need to download and install the free Java JDK from the Oracle/Sun website. As of November, 2012, you will find that website at http://www.oracle.com/technetwork/java/javase/downloads/index.html

Back to Question 2

Answer 1

False. You can write Java code using any plain text editor. You simply need to cause the output file to have an extension of .java.
